Weather shield

from Wikipedia, the free encyclopedia

A weather panel , also weather choke called, is a weather-technical structure, which in mining underground to regulate the weather turn is used. The cross-section of the route is severely narrowed by weather screens , so that the weather resistance increases and less weather flows into the mine structures concerned . Weather screens can also be constructed in such a way that they completely seal off the area in front of which they are used.

Structure and use

Weather screens are constructed in a similar way to weather doors , however, weather screens usually do not allow driving . They are mostly made of brick or wood that has been assembled into a shed . The miner also calls brick weather throttles a throttle wall . The use of wooden weather screens is only advisable for smaller track cross-sections due to the high load. If part of the weather is to be passed through the weather screen, they are provided with an opening. In order to be able to regulate the amount of weather flowing through, so-called sliding hatches are used instead of rigid openings, these are sheet metal plates that can be pushed back and forth. If only the weather speed is to be reduced by the weather shield, they are designed in such a way that they do not shield the entire cross-section of the route, but only parts of it. The miner calls such constructions weather bounces . Weather screens are often used to seal off cuts that are no longer needed (short connection between two pit structures) to the old man . In addition, weather screens are also used to prevent the fresh weather and the downweather from mixing by means of a simple construction.
